I implemented custom image fetcher (DFImageFetching) but DFImageManager doesn't reuse existing operations/can't lookup image in memory cache.

Verify that `isRequestFetchEquivalent:toRequest' method is implemented correctly (required for reusing fetching operations)
Verify that `isRequestCacheEquivalent:toRequest' method implementation is valid (required for memory cache lookup)
Verify that your resource implements -hash method.
